We compared the top crypto tax software for 2025 — Koinly, CoinTracker, and Crypto.com Tax — on asset support, integrations, pricing, and tax-loss harvesting. Koinly takes the top spot for its broad exchange coverage and smart transfer matching. CoinTracker is the best choice for Coinbase users. Crypto.com Tax is the best free option with unlimited transactions. Note: affiliate links are available for Crypto.com Tax; Koinly and CoinTracker picks are included editorially without affiliate links as their product IDs were not available in the system.
crypto taxes are a headache. capital gains, airdrops, staking rewards, DeFi yields — every transaction type gets treated differently by the IRS (and most other tax authorities). manually sorting through hundreds or thousands of trades across multiple exchanges is not realistic for most people. that's where crypto tax software comes in.
we looked at the three most talked-about options to find the best fit for different kinds of users.
before we get into the picks, here's what actually matters:
koinly supports more than 350 crypto exchanges and wallets and is available in 20 countries.1 it handles over 17,000 assets and uses AI-powered smart transfer matching to figure out which transactions belong together — useful if you move crypto between wallets and exchanges frequently.
the free tier covers up to 10,000 transactions, and paid plans start when you need to generate tax reports. it's the most geographically flexible option on this list, which makes it the default recommendation for most people.
cointracker is the official tax partner of Coinbase, so if you're primarily on Coinbase or Coinbase Pro, the integration is seamless.2 it doubles as a portfolio tracker, which means you can keep an eye on your holdings year-round and generate tax reports when needed.
it's a strong choice for US-based users who want something that just works with their existing exchange. the portfolio tracking dashboard is polished and gives you a real-time view of your unrealized gains and losses.
crypto.com tax is completely free with no restrictions on the number of transactions.3 that's rare in this space — most "free" tiers cap you at a few hundred or thousand transactions before asking for payment.
if you're a crypto.com user, the integration is native and automatic. but even if you're not, it supports imports from other exchanges and wallets. the trade-off is that it's less feature-rich than the paid options above — you won't get the same depth of tax-loss harvesting analysis or multi-country support.
